MILK-BOTTLE-GAP REMOVE-R. 7

Specification of Letters Patent. 7

Application filed March 12, 1918. Serial No. 221,887.

To all whom it may concern Be it known that I, JAMES F. EINFELDT, acitizen of the United States, residing at the city and county of SanFrancisco and State of California, have invented new and usefulImprovements in Milk-Bottle-Cap Removers, cation.

This invention relates to a means for removing the normal closures frommilk containing bottles and the like; and has for its object to lift thecap bodily from its seat and to retain it in such a position as to beeasily replaced and released.

It consists of a preferably convex disk of such a diameter that it maybe introduced into the sunken seat, above the normal closing cap uponwhich its periphery rests. Within the convexity is an elastic curvedarm, having apointed end, and means for turning and advancing the arm sothat the point will pierce the material of the closure approximatelyparallel with the surface. i inclined slot is made through the side ofthe cap and the operating arm projects through this slot so that by itsaid the interior pointed arm will be pressed down by the inclined traveland will thus be forced into the material of the receptacle closure insuch a manner that the lifting of the utensil, by means of a suitablehandle, will bring with it the closure which is held closely against theremover, and may be replaced by it, and afterward released so as toremain upon its seat.

In the accompanying drawings:

Figure l is a vertical section.

Fig. 2 is a bottom view of the utensil.

ig. 3 is a modified form.

Milk and like containers usually have wide mouths and an interior flangeor shoulder upon which the circular closure rests, fitting closelyenough to maintain its place and prevent the escape of the contents.These closures are usually made of some fibrous, flexible material, likepasteboard, and after being seated are difiicult to remove without beingdestroyed and splashing some of the contents.

In the present invention a centrally journaled arm A, having a curvedportion 2 at the outer end and a sharp terminating point 3, is turnablein a disk-like support 4, the exterior of which is of such a diameterthat it will enter the mouth of the container and will rest upon thatportion of the closure of which the following is a specifiwhich issupported upon the interior shoulder of the container. The arm 2 beingthen turned a short distance and being elastic will force the pointedend 3 into the top of the closure, in such a manner that when the diskis lifted itbrings the closure adhering to it.

The elastic action of the arm is making an inclined slot 5 in the of thedisk, through which an arm 6 point engage the closure, or retracted torelease it.

The form of the disk may be varied. It is here shown as arched, so thatthe arm 2 may be contained in the concavity. A vertical journal. orequivalent. bearing guides the arm when turned and the projecting arm Aextends out through the slot 5, as before described. A central knob orhandle 7 serves to its use.

Having thus described my invention, what I claim and desire to secure byLetters Patent is- 1. In a milk bottle cap remover, a conaided byperiphery operating projects and is so connected with the 3 that thelatter may be advanced to guide and hold the disk during Patented Jan.14,1919. 7

cavo-convex member formed to enter the mouth of the bottle and to seaton the bottle cap, said member having an inclined slot on a sidethereof, and an arm journaled at the center of the member and having anoperating part extending through the inclined slot and also formed witha terminal point adapted to penetrate the cap upon the arm being movedthrough the slot.

2. In a milk bottle cap remover, a member formed to overlie the mouth ofthe bottle and having an inclined guide, and an arm journaled in themember and having a part engaged with the guide and a point adapted topenetrate the cap uponsaid part of the arm being moved to engage theguide and being guided in its movement thereby.

3. In a milk bottle cap remover, a member having an arm movablyconnected thereto and having a point operating in an inclined plane, andmeans on'said member to guide the arm whereby to move said point in aninclined plane to cause same to enter the cap.

4. In a milk bottle cap remover, an oscillatory arm, a member supportingthe arm,

said arm having a point, and guiding means ling t0 the member,

and when the arm is at the other end of the guide the point will lieabove the cap.

5. In a milk bottle'cap remover, a memher having an arm rotatablyconnected thereto at one end, an inclined point extending outwardly fromsaid arm, and means to operate the arm whereby upon partial turningthereof the point will move downwardly in an inclined plane andpenetrate the cap.

6. In a bottle cap remover, a supporting member, a wire and rotatablyconnected at its point 01": doub said member having a Copies of thispatent may be arm doubled upon itseltv obtained for five cents each, byaddressing the witnesses.
